Biocontrol Activity of Three Endolichenic Fungi from Peltigera

Abstract

Three strains of endolichenic fungi identified as Creosphaeria sassafras, Annulohypoxylon multiforme and Penicillium vulpinum, were isolated from samples of Peltigera species collected from Shennongjia forest region in Central China. The anti-pathogenic microorganic activities of them were assessed by the methods of culturing with their fermentation broth and plate confrontation co-culture against four pathogenic fungi. The results showed that some strains had more obvious inhibitory effect than positive control strain Chaetomium globosum. We conclude that some endolichenic fungi have the potential for use in developing a novel therapy to control plant disease and saprolegniasis.
